Title
Recent Development on Modified Ghost Fluid Method
Abstract
It is still extremely challenging in modeling and simulating moving material interfaces with large density ratios and strong wave interaction. The Modified Ghost Fluid Method (MGFM) has provided us a robust way of handling such challenges and overcomes the difficulties encountered by the original ghost fluid method proposed by Fedkiw et al. The MGFM has successfully applied to treat moving gas-gas, gas-liquid and fluid-structure inferfaces in compressible fluid/media.
In this talk, I shall introduce the latest development and applications of the MGFM, including fast explicit Riemann problem sover to predict interface states, exact Riemann problem solver for treating elastic-plastic material, the coupling between compressible fluid and incompressible fluid.
